12 Claims.

In that type of hollow structure used for caissons, piers, and the like where the same are tapered or battered it has usually been the custom to build the same of wood, or in great part of wood, owing to the complications incident to constructing a tapered form in metal.

The object of the present invention is to provide a structure of the above character that makes it entirely feasible to employ metal parts, preferably deformed plate metal, in that the elements or members making up the side walls can be of a standard length while the tapering formation of the structure as a whole is obtained.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of a tubular form.

Figure 2 is a vertical sectional View therethrough.

29 Figure v3 is a horizontal sectional view on the line 3 -3 of Figure 1.

Figure 4 is a detail vertical sectional view-on the line 4-4 of Figure 1. V

Figure 5 is a vertical sectional view on the line 325 5-5 of Figure 1.

Figure 6 is a detail perspective View of one of the side wall plates.

Figure? is a top plan view of the same. FigurejS is a longitudinal sectional view on the 130 line 8-8 of Figure 6.

Figure 9 is a perspective view of one of the corner posts.

Figure 10 is a top plan view of the same.

Figure 11 is a bottom plan View.

"Figure 12 is a rear elevation of one of the wall plates.

,Figures 13, 14 and 15 areplan views of plates of different lengths which may be standardized for erecting forms of different cross "sectional area.

Figure 16 is a detail view illustrating the employment of intermediate reinforcing means for the side walls.

While the form obviously can take any desired cross sectional configuration, in the embodiment disclosed it is square, and four corner posts designated 17 are provided, these posts corresponding in structure and form.

Each post consists of outer right angularly disposed side walls 18 that are longitudinally tapered and are joined together to produce a corner. Extending rearwardly from the outer edges of the walls 18 are longitudinally disposed flanges 19 preferably, though not necessarily, of the same width throughout their lengths, these flanges 19 thus converging toward the upper end of the cornerposts. The corner posts as indicated in Figure 1 may be made of sections secured to,- gether, as by Welded joints 20.

When the posts are set up, it will be evident 55 by reference to Figure 3 that the flanges of one post are in opposition to the flanges or" the ,Ofiher post, and while they are-transversely convergent, they areparallel in a longitudinal direction. In other words the width of the space between the .opm i sfia ss o a a n os re ai the same th h ut t en t o h re- This spa i cfil sd :b w l p at r memb s .21- Eflfih m mb a llbfi clea by e en t Fi u e 6. 7 n 8, i :Q hannel d mat n 5 mpri in asine al 22 dl ne d a rea w r ly urne id flan e 2. The end o the plates have rearwardly turned end flanges 2 which have their ends preferably electrically welded to the ends of the flanges 23. Theend it; flanges 251 are set at an acute angle to the facing wall 22 and are disposed at the same convergent angles the side flanges 19 of the corner posts (see Figure 3), against which they abut. The flanges 19 and 24 are secured together by any suitable means, as bolts 25, and the side flanges 23 of one plate are likewise secured to the flanges o the upp and lowe ad o n ate by be .or other fasteners 26.

By means of this structure, it will benoted that 55. the wallplatesZl are of the same length throughout the height of the structure, thus making it possible to provideaplate ofstandard length in,- stead of plates successively shorter. It will be understood,'howev.er, that these wall plates maybe 9,? made up in different lengths so that instead of a square structuraan oblong or other form maybe provided. Thus in Figures 13, 1,4 and 15 there are shown such wall plates 21a, 21b and 210, any set of which of equallength may be employed merfily 9.5

by spacingthe corner posts farther apart or closer together, as the case may be. Thus a longer set of plates maybe used-for two of the sides than for the other two sides. And as will be obvious it is not necessary that the structure should be rectangular for by providing the necessary number of posts, a pentagonal, hexagonal or octagonal structure may be produced.

In the disclosure shown in Figure 1, a complete form is illustrated and this may be held at its bottom by vertical anchoring beams 27 embedded in the foundation for the form and extending upwardly inside and against the different lower side plates.

Where the outside pressure is great or the gig length the side plates is extended, in order to prevent buckling, the plates may be backed by vertical reenforcing bars as illustrated in detail in Figure 16. In this case the side flanges designated 23a are cut away at intervals and vertical reenforcing beams 28 are placed transversely of the plates and against the outer walls thereof. In such a structure it will be understood that recesses 23b provided are alined in the different plates. either to the full height of the structure or to such a point as may be found desirable.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
